APSUB-CH41
Troubleshooting
1. Low volume setting on radio is too loud - Set the minimum volume using process outlined in Setup and Configuration, or using
the AmpPRO PC app.
2. If for any reason the APSUB module becomes unresponsive, or will not power up with the key on, you can reset the interface
by turning the key to the ignition position, then pressing and holding the Volume Down button on the factory steering wheel
controls for 12 seconds until a tone is heard or by pressing and holding the reset button on the side of the APSUB module for
10 seconds (until the LEDs alternate flashing red).
